DeepCool N1 cooling pad replacement feet

Had this cooling pad for about 4 years.

I broke one foot by accident while trying to detach it. So I've made a replacement one.
It fitted so well and it was so stiff that I've broke the other one too just to replace it.
As a pivot, I've used some old allen bars hanging around, mounted from inside of the case.

Also, I cannot explain why this 4 year cooling pad retails at double the price I've initially bought it.
